Inspired by the recent discovery of a 5th(!) Extra Terrestrials cart, I wanted to put together a quick list of all of the R10/top tier rarest carts arranged by the number of publicly known copies. I greatly look forward to hearing from those who know far better than I here about more exact figures, and certainly about the estimated number of copies for games that are usually among those featured on all of the "rarest Atari games" lists. What I have off the top of my head and from quick searches:
1x copy: Gamma Attack, Red Sea Crossing, Cat Trax (was this real?)
2x copies: Birthday Mania, monogrammed Space Chase
3x copies: Ultravision Karate
5x copies: Extra Terrestrials
6x copies: Gauntlet
15x copies: Eli's Ladder
23x copies: Magicard
28x copies: Pepsi Invaders
and with a surprising amount of copies apparently out there, around 20x copies of Air Raid known.
